DENSO Auto Parts Air / Fuel Ratio Sensor P/N:234-5137
DENSO Auto Parts 234-9062 air / fuel ratio sensor for the 2007-2009 Honda CR-V 4-cylinder 2.4L reads the air-fuel ratio in the exhaust and passes it to the engine computer. The computer uses that reading to adjust fuel delivery.
A lit check engine light, rough running or poor fuel economy can mean this sensor is worn out, though the downstream oxygen sensor or a vacuum leak can sit behind those signs as well. Pin down the cause before you buy a new sensor.
This is a direct-fit replacement for the 2007-2009 Honda CR-V 4-cylinder 2.4L.
